The word "Lai" in ancient poetry

1. But now I remember that night, that storm, and I wonder how many flowers were broken.

Blow open the petals of ten thousand pear trees, just like the strong wind in spring, blowing at night.

The clouds began to sink, and the rain was coming.

4. I know it's far away, but I also want to collect my bones by the river.

Igbo returned to the flying flag and looked from the air.
